SAFETY RAZOR ACCESSORY Sidney 11. Benjamin, Milwaukee, Wis. Application May 4, 1939, Serial No. 271,701

9 Claims.

My invention relates to safety razors and refers particularly to unitary constructions of some of the elements of safety razor blade accessories.

One of the objects of my invention is a unitary construction of a. safety razor cap and guard, a safety razor blade carrier, and blades therein, said elements being so maintained as not to be accidentally disassembled under ordinary han- 10 dling and being capable of being-readily disassembled if desired.

-Another object of my invention is such a unitary construction as is capable of insertion within a recess within the handle of a safety razor, which canbe readily inserted into and removed from such handle recess without disassembling the elements of the unitary construction and which will not become so disassembled while within said recess during the handling of said handle.

Another object of my invention is a unitary construction of a safety razor cap, a safety razor guard, a safety razor blade carrier and blades therein in which these elements are so removably positioned with respect toeach other that when so assembled they are maintained in practically immovable relationship with respect to each other. v

, Another object of my invention is a unitary construction of asafety razor cap, a safety'razor guard, and a. safety razor blade carrier and blades therein, so removably assembled that when so assembled the said safety razor blade carrier is maintained in" immovable horizontal and vertical position with respect to said'cap and guard.

While these are the specific objects of my invention, I do not limit myself to such applications of the devices of my invention.

. I refer, therefore, to this 40 devices of my invention.

Attempts have been made to produce a safety razor of such construction that the entire razor head, including the cap and the guard, with'or without a positioned blade, and a blade. carrier 4,5 may be inserted within a recess withinthe handle, the advantages of such a construction being generally recognized.

I Thechief difficulty \that has been met in pro. ducing a safety razor of this construction has been the inability to prevent the various elements from moving with respect to each other while thus inserted in the handle recess.

It isevident that ii the cap and guard are not immovably connected, the separation of 55 these elementswill allow a blade carried between specific use of the,

them; to contact the inner face of the handle recess thus dulling and injuring it and making it unfit for further'shaving operations, and hence the cap and the guard must be maintained from vertical, horizontal, and rotatable movement '5 with respect to each other, that is,-they must be of an immovable unitary construction with respect to each other.

A blade carrier must be of such a construction that it be adapted-to maintain a plurality 1 of wrapped or unwrapped blades while allowing of their removal for use.

It is evident, therefore, that means must be employed to prevent the accidental removal of the blades from the blade carrier during the 15 handling of the handle, in order to prevent them from being injured by contact with the recess wall. 4

-It is further evident that if these several elements of a safety razor and blades become dis- 20 engaged, or are not connected they will move around within the recess and hence will be subject to damage.

It is to be noted from the above that the only solution of the difliculties thus presented is a 25- unitary construction of the guard, inserted blade and a blade carrier as will prevent any vertical, horizontal, rotary or other movement of these elements with respect to each other under ordinary usage and especially while inserted 80 within a recess within the handle. My invention overcomes all of the above, and other, difliculties and presents a unitary construction capable of being inserted within a recess within a safety blade handle and which are '35 so removably attached to each other that they will remain in stationary positions with respect to each other during ordinary handling of the razor handle within which they are positioned, while allowing 01' their proper disengagement 40 when desired. y In the accompanying drawings I illustrate modified forms of the devicesof my, invention, but I wish to be understoodth'at I do not limit myself tothese particular forms of construction as" it is evident that variations and changes may be made therein without going'beyond the scope one form of'a device of my invention. i

Figure 17 is a vertical section through a modifled form of a device of my invention.

The particular form of a device of my invention disclosed in Figures 1 to 8 comprises a safety razor cap having the longitudinal elongated element 2? and the two dependent end lug members 2i and 2i the terminal inner faces of which are flared slightly inwardly forming the attaching members 22 and 22. The under side of the cap has a longitudinally positioned elongated recess 23 extending between the end lugs 2i and 2i.. A threaded stud 2Q extends outwardly from the central portion of the recess 23 and is adapted to attach the cap, a blade and a later described guard member to a handle 25.

A further element of this form of a device of my invention is a guard element comprising the longitudinally elongated member 28 having a plurality of spaced teeth or prongs 21, 21', 21 on each side thereof and a plurality of extended lugs 28. 28, 28 ada ted to extend through a corresponding plurality oi openings in a later described razor blade and into the recess 23 of the cap. The guard has also an opening 29, so positioned as to allow the stud 24 of the cap to extend therethrough. The uard fits snugly between the end lugs 2!, 2! of the cap,

In the employment of my device for shaving purposes. a razor blade 30 having a plurality view of the cap of Figures of openings 3|. Si. Si to allow of the passage of the lugs 28. 28, 28 of the guard therethrough, is positioned between theiguard and the cap as shown.

A further element of this form of the device of my invention comprises a blade carrier comprising a bottom member 32, the end member 33 and the two side members SI, 34 which are bent inwardly toward each other forming the two spaced top members 35, 35. The bottom member 32 has an opening 88 adapted to receive the stud 24 of the cap.

The blade carrier is of such length that it can be forcibly passed downwardly between the through a modilugs elements 22, 22 of the cap and when so positioned is frlctionally maintained between the lugs 2i, 2| of the cap and thus prevented from accidental removal therefrom.

The upper portion 3! of the handle 25 is extended into a conical or pyramidal form and has an internally threaded opening 38 to receive the stud 2d of the cap.

The blade carrier is adapted to receive a plurality of wrapped or unwrapped blades 30, 30.

The unitary construction or this form or my device comprises a cap having extended end lugs and a centrally positioned extended threaded lug, a toothed guard positioned between the end lugs oi the cap with the threaded lug of the cap extending through a hole within said guard and a blade carrier, with or without blades, positioned upon the guard and between the end lugs oi the cap, said blade carrier being frictionally maintained in place and thus holding the cap, the guard and the blade carrier into a unitary construction.

It is evident that a blade may or may not be positioned between the cap and the guard in this unitary construction.

One useful application of this unitary construction is shown in the drawings in which this construction is inserted within a recess 35A of the handle 25, the open end of which has the removable closure 36A.

While in Figures 1 to 8 I have disclosed and explained a form of my device in which the cap has a threaded lug capable of being threaded to the handle by means of an internally threaded recess in the latter, it is evident that this particular form of construction of the cap and handle is not necessary in the formation of my unitary construction, and that the exteriorly threaded lug may be carried by the handle and the interiorly threaded recess may be a portion of the cap.

This construction is shown in the form of my device as illustrated in Figures 9, 10 and ii.

In this form the cap 26 has an internally threaded recess 38A and the handle 25 has an extended exteriorly threaded stud 24A capable of being threaded within the recess 33.

As the opening 36 in the blade carrier in the first described form of my device was adapted for receiving the stud 24 oi the cap which extended through the guard and the blades in the carrier, and as the threaded stud of this modified form does not extend through the guard, the

extended connecting lug 39 being a part of the handle 25, it is evident that in this form of my device, it is not necessary for the bottom of the blade carrier to have an opening therethrough.

In the modified form of my device illustrated in Figures 13, 14 and 15, the cap. the guard and the handle are similar to those shown in Figures 1 to 8 with the exception of the means for producing a unitary construction.

In this form. of my construction the blade carrier comprises a bottom member ill, the end member GI, and the side members l2, 42. The central portions of the side members 42, 42 are bent inwardly toward each other forming the two spaced top members 43, J3. The two end portions of each side member 42 are bent to form a somewhat curved resilient clasping members or teeth of the guard, thus resiliently removably to each other,

connecting the blade carrier to the guard, and as the guard is frictionally attached to the cap, the elements are maintained in removable unitary construction by both resilient and frictional means.

In the modified form of a device of my inventlon illustrated in Figures 12, 14 and 16 the cap, guard and handle are similar to those shown in Figures 9, and 11, the exteriorly threaded stud being upon the handle and hence the blade carrier does not require an opening in the bottom thereof, and the unitary construction is similar to that described above.

In the modified form of a device of my invention shown in Figure 17, the clasping' members 44, M of the device shown in Figure are extended into the clasping members 45, 45 which extend around the outer edge of the cap.

It is evident that my invention is not limited to double edge blades as shown and described, and that it is equally applicable to single edge blades.

It is also evident that my invention is not limited to the particular form or function of the cap and guard or to any particular means for maintaining the blade in fixed position for purposes of shaving. I

It will thus be seen that my invention presents a unitary construction of a safety razor cap, a safety razor guard, a safety razor blade carrier, and blades therein so arranged that they are practically immovably attached to each other when assembled in the unitary construction, such attachment preventing the elements from vertical, horizontal or revoluble movement with respect while the elements may be readily removed from each other if desired.

By "unitary construction" in my specification and claims I'mean such an assembly of the elements as will maintain them in fixed relationship to each other during its ordinary handling and storage, while the construction. however, will allow the ready disassemblage of the elements when desired.

' I do not limit myself to the particular size, shape, number, arrangement, or material of parts as specifically shown and described as these are given simply as a means for clearly describing the devices of my invention.
